French plane manufacturer Airbus expects engines of grounded A320neos to be replaced by April, a top company executive said on Thursday. Airbus India president and managing director Anand Stanley said 95% of the retrofit job has been completed by the US-based engine manufacturer Pratt & Whitney, which supplies engines for the A320neos. \u201cThere is commitment from P&W that retrofitting work will be completed by April. All the known and reported issues would be rectified by then,\u201d Stanley told reporters at the sidelines of FICCI\u2019s Wings 2019 summit.

Low-cost carriers IndiGo and GoAir have been facing engine troubles on their A320neo fleet for more than a year now. Several of their aircraft have had to be grounded due to mid-air shutdown of engines. While market leader IndiGo has 71 A320neo aircraft in its fleet, Mumbai-based GoAir possesses 35 of the narrowbody jets. Last month, the Directorate General of Civil Aviation forced airlines to make extra checks on their Airbus A320neo aircraft fitted with P&W engines, as part of new safety protocols.
